How do I make a JBoss Quartz job see classes in my JAR file? - jboss

Question

I'm using JBoss 4.2.3.GA and deploying a JAR application, which uses Hibernate 4.1.5.SP1. In my JAR, I have a Quartz job, configured like so ...
#MessageDriven(activationConfig = {#ActivationConfigProperty(propertyName = "cronTrigger", propertyValue = "0 40 12 * * ?")})
#ResourceAdapter("quartz-ra.rar")
#Depends({
"jboss.ejb:service=EJBTimerService"})
public class UpdateOrgsJob implements Job {
I think JBoss loads Quartz in a separate classloader than where my JAR classes get referenced, because, I get the error "java.lang.NoClassDefFoundError: net/sf/ehcache/CacheException" even though it is in my JAR file. How do I make my JAR classes visible to Quartz?

Answer 1

you can put your ehcache jar file in ${jboss.server}/lib, Or you can also try the 2 methods mentioned in the Jboss wiki
1. Delay Quartz service startup
2. set <attribute name="UseJBossWebLoader">true</attribute>
